Writeup from MB 100:
Northwest Africa 7259 (NWA 7259) Morocco Found: 2010 Classification: HED achondrite (Eucrite, polymict) Physical characteristics: Half fusion-crusted stone. Petrography: The texture is typical of polymict eucrite breccias, with diverse basaltic-gabbroic textures represented among clasts. Pyroxenes mostly show typical noncumulate-eucritic exsolution. Geochemistry: Low-Ca pyroxene (based on 7 analyses) ranges from En48Wo3 to En34Wo3; high-Ca px (5) from En36Wo44 to En29Wo44; plagioclase (9) from An87 to An91. Avg. pyroxene Fe/Mn (wt. ratio) = 29.8. Classification: Polymict eucrite breccia. | ||||||||||||||||||||||||||||
